Total Questions: 50

21. Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL 04/08/2023 (2nd Shift)]

Correct Answer: (b) 43 - 82
Solution:The pattern followed here is :
(1st number × 2) - 3 = 2nd number
(39 - 75) → (39 × 2) - 3 = 75
(55 - 107) → (55 × 2) - 3 = 107

(64 - 125) → (64 × 2) - 3 = 125
But,

(43 - 82) → (43 × 2) - 3 = 83 (Not 82)

Hence, (43 - 82) is the correct answer.

22. Based on the alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which of the following does NOT belong to that group [S.S.C CHSL 04/08/2023 (2nd Shift)]

Correct Answer: (a) JLN
Solution:The pattern followed here is :

But,

Hence, JLN is the correct answer.

23. Based on the alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which of the following does NOT belong to that group? [S.S.C CHSL 04/08/2023 (4th Shift)]

Correct Answer: (b) ABD
Solution:The pattern followed here is :

But,

Hence, ABD is the correct answer.

24. Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL 04/08/2023 (4th Shift)]

Correct Answer: (a) 9 - 44 - 218
Solution:The pattern followed here is :
(1st number × 5) + 1 = 2nd number

(1st number × 5) + 1 = 3rd number

(6 - 31 - 156) → {(6 × 5) + 1 = 31}, {(31 × 5) + 1 = 156}

(13 - 66 - 331) → {(13 × 5) + 1 = 66}, {(66 × 5) + 1 = 331}

(16 - 81 - 406) → {(16 × 5) + 1 = 81}, {(81 × 5) + 1 = 406}

But,

(9 - 44 - 218) : {(9 × 5) + 1 = 46}, {(46 × 5) + 1 = 221} (Not 218)

Hence, 9 - 44 - 218 is the correct answer.

25. Based on the alphabetical order, three of the following four are alike in a certain way and thus form a group. Which is the one that does not belong to that group? [S.S.C CHSL 07/08/2023 (1st Shift)]

Correct Answer: (a) HJN
Solution:The pattern followed here is :

But,

Hence, HJN is the correct answer.

26. Select the option in which the numbers do not share the same relationship as that shared pairs of numbers. [S.S.C CHSL 07/08/2023 (1st Shift)]

(Note: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)

11 : 35 and 13 : 41

Correct Answer: (c) 32 : 95
Solution:The pattern followed here is :
(1st number × 3) + 2 = 2nd number

(11 : 35) → (11 × 3) + 2 = 33 + 2 = 35

  • 13 : 41 → (13 × 3) + 2 = 39 + 2 = 41
  • 32 : 98 → (32 × 3) + 2 = 96 + 2 = 98 (Not 95)

27. Three of the following four are alike in a certain way and thus form a group. Which is one that does not belong to that group? [S.S.C CHSL 07/08/2023 (1st Shift)]

(Note: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)

Correct Answer: (a) 13 - 144
Solution:The pattern followed here is :
(1st number) × (1st number - 2) = 2nd number

(9 - 63) → (9) × (9 - 2) ⇒ 9 × 7 = 63

(8 - 48) → (8) × (8 - 2) ⇒ 8 × 6 = 48

(11 - 99) → (11) × (11 - 2) ⇒ 11 × 9 = 99
But,

(13 - 144) → (13) × (13 - 2) ⇒ 13 × 11 = 143 (Not 144)

Hence, 13 - 144 is the correct answer.

28. Three of the following four are alike in a certain way and thus form a group. Which is one that does not belong to that group? [S.S.C CHSL 07/08/2023 (3rd Shift)]

Correct Answer: (a) 444 : 339
Solution:The pattern followed here is :
(1st number - 2nd number) = 107

(189 : 82) → 189 - 82 = 107

(401 : 294) → 401 - 294 = 107

(500 : 393) → 500 - 393 = 107

But,

(444 : 339) → 444 - 339 = 105 (Not 107)

Hence, (444 : 339) is the correct answer.

29. Three of the following number pairs are alike in some manner and one is different. Select the odd number pair. [S.S.C CHSL 07/08/2023 (3rd Shift)]

Correct Answer: (c) 86 : 252
Solution:The pattern followed here is :
(1st number × 3) - 1 = 2nd number

(72 : 215) → {(72 × 3) - 1} ⇒ 216 - 1 = 215

(99 : 296) → {(99 × 3) - 1} ⇒ 297 - 1 = 296

(115 : 344) → {(115 × 3) - 1} ⇒ 345 - 1 = 344

But,

(86 : 252) → {(86 × 3) - 1} ⇒ 258 - 1 = 257 (Not 252)

Hence, (86 : 252) is the correct answer.

30. Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group? [S.S.C CHSL 07/08/2023 (3rd Shift)]

Correct Answer: (b) LNQ
Solution:The pattern followed here is :

Hence, LNQ is the correct answer.
